Pruitt, floated as a potential pick to head the Environmental Protection Agency, said that he is looking forward to the "regulatory rollback" that will likely happen under Trump.

"So we've been involved ... as you know, in suing the EPA, in suing under the Affordable Care Act to make sure that our citizens are protected and the states are protected, and now we have hope that there is going to be regulatory rollback," Pruitt said in an interview with radio host John Catsimatidis.

"The greatest opportunity that we have heading into this new administration, John, is to provide certainty to business industries across this country," he said.

Pruitt said he would like to see a set of limitations imposed on the EPA, an agency he has fought in court as Oklahoma's attorney general.

"Well when you look at the EPA, and the role that it’s played over the last several years, there’s going to be substantial change in that agency. There’s going to be a regulatory rollback, and it needs to occur in the ways that we describe," he said.

"The leaders of the EPA, the leadership of the Department of Energy, is going to be substantially important as we head in to this new administration. There should be much hope and optimism across the country for jobs and economic growth because Washington is going to be less consequential," he added.

Pruitt has previously criticized the EPA for executive overreach and for the agency's regulations. In 2015, Pruitt sued the EPA for its attempt to redefine water, arguing that the new policy is an "unlawful attempt" to expand federal bureaucracy.

“The Clean Power Plan is an unlawful attempt to expand federal bureaucrats’ authority over states’ energy economies in order to shutter coal-fired power plants and eventually other sources of fossil-fuel generated electricity,” he said in a statement last year.
